如何提高轻钢结构的耐火性能

来源:http://www.jnghbxg.com 日期:2018-12-20 发布人:admin 浏览次数:
目前钢结构的使用情况越来越普遍,因为安装快捷,使用方便,比较环保,对于轻型钢结构来说,防火性是比较重要的,怎么提高防火性呢?
At present, the use of steel structures is becoming more and more common, because the installation is fast, easy to use, more environmentally friendly, for light steel structures, fireproof is more important, how to improve fireproof?
1、发泡防火漆法:防火漆是由成膜剂、阻燃剂、发泡剂等多种材料制造而成的一种阻燃涂料。而使用这种漆料的主要原因是一旦将防火漆涂于物体表面,一旦发生火灾,的确能在定时间里阻止火势蔓延,保护物体表面。
1. Foaming fire-retardant paint method: Fire-retardant paint is a kind of flame-retardant paint made of film-forming agent, flame retardant, foaming agent and other materials. The main reason for using this kind of paint is that once the fire retardant paint is applied on the surface of the object, once a fire occurs, it can prevent the spread of the fire and protect the surface of the object in a certain time.
2、外包防火层法:即在轻型钢结构外表添加外包层,可以现浇成型,也可以采用喷涂法。现浇成型的实体混凝土外包层通常用钢丝网或钢筋来加强,以约束收缩裂缝,并保证外壳的强度。同时外包层也可以用珍珠岩、石棉或石棉水泥、轻混凝土做成预制板,采用胶粘剂、钉子、螺栓固定在钢结构上。

2. External fire protection layer method: that is, adding outer layer on the surface of light steel structure can be cast in situ or sprayed. In order to restrain shrinkage cracks and ensure the strength of the shell, the cast-in-situ solid concrete outer layer is usually strengthened by steel wire mesh or reinforcing bar. At the same time, the outer layer can also be made of perlite, asbestos or asbestos cement, light concrete into prefabricated panels, using adhesives, nails, bolts fixed on the steel structure.
至于怎么提高轻型钢结构的防火性,以上详细分享了两点,希望能帮到大家,我公司可搭建轻型钢结构,欢迎前来我公司洽谈合作。
